Signatures morphosédimentaires de la dynamique juxta-glaciaire à la transition de fronts glaciaires marins à terrestres : le cas de la Côte-Nord du Québec (estuaire et golfe du St Laurent)
Bibliographic record
Abstract
This thesis combines a dual geomorphological and sedimentological approach with the use of LiDAR data, bathymetry, drone photogrammetry and radiocarbon dating. It has enabled us to reconstruct the glacial paleodynamics in a deglaciation context for the Laurentide ice sheet since the last glacial maximum, around 20,000 years ago, and more specifically during the transition from an ice margin anchored at sea to a continental ice margin: (1) mapping, synthesising and proposing a model for the megagrooves of the North Shore of the St Lawrence, a first study for these morphologies, and (2) reconstructing the geomorphological and morphosedimentary record of the Pentecôte sedimentary complex, which precisely represents this transition. Overall, this thesis demonstrates the importance of the structural heritage and physiography of the floor at the glacial margin in the reconstruction of the glacial retreat dynamics of the eastern LIS margin.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
